* dynamic window manager is designed like any other X client as well. It is

* manager like dwm selects for SubstructureRedirectMask on the root window, to
|
||||
* receive events about window appearance and disappearance. Only one X
|
||||
* connection at a time is allowed to select for this event mask.

* Due reading status text from standard input, a select-driven main loop has
|

* been implemented which selects for reads on the X connection and
|
||||
* STDIN_FILENO to handle all data smoothly and without busy-loop quirks. The
|
||||
* event handlers of dwm are organized in an array which is accessed whenever a
|
||||
* new event has been fetched. This allows event dispatching in O(1) time.

|
